Argan Oil
For dry, colored hair, environmental aging of hair fibers can have significant effects on their condition and mechanical properties, such as strength and softness. This type of hair is particularly vulnerable to damage from environmental pollutants and sun exposure. To improve the health and appearance of dry, colored hair, it may benefit from the addition of argan oil. This oil can help improve the hair fiber's ability to retain moisture, resulting in better suppleness and increased shine.
